Contains the spz signal peptide (aa 1-29), followed by a triple Tag:V5 tag, and N-spz (aa 30-147) expressed under the control of UASp regulatory sequences.
Embryos overexpressing spzN.Scer\UAS.P\T.T:SV5\V5 under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 show normal cuticle patterns and are viable.
